PHOSPHOROUS OXYCHLORIDE Resistant O-Rings and Seals

Phosphorous oxychloride, also known as POCl3, is an inorganic compound used in the production of organophosphorus compounds and as a reagent for various organic syntheses. Common industrial uses for phosphorous oxychloride include the production of fertilizers, pesticides, and other industrial chemicals.

When rubber is exposed to phosphorous oxychloride, it can cause the rubber to become brittle and can lead to cracking or complete breakdown of the rubber material. Additionally, it can cause severe swelling which can lead to permanent deformation of the rubber. The acidic nature of the phosphorous oxychloride can also accelerate degradation of the rubber and can cause premature failure of the rubber material. Additionally, the corrosive nature of the compound can cause the rubber to become embrittled and can cause discoloration and staining of the rubber.
